Tips to buy Solar Panels

Published on March 27, 2015, by in Tools.

Tips to buy Solar PanelsSolar panels generally refer to a solar hot water panel, a photovoltaic module or a set of photovoltaic modules which are electrically connected and are mounted on a supporting structure, such as on the roof of the building, or freestanding. Solar panels have gotten lighter and more efficient, but it is still a good idea to consult with a local contractor like Feller Roofing to be sure your roof is structurally sound enough to carry the load. They can be used as a component of a larger system of photovoltaic modules to generate and supply electricity for residential and commercial applications. Each module is rated under standard test conditions by its DC output which ranges from 100 to 320 watts. A single solar module can generate only a limited amount of power. A typical photovoltaic system consists of a panel or an array of solar modules, an inverter and sometimes a battery or solar tracker with interconnecting wirings. 12V solar panels are considered to be the best ones among a lot of them.

So what are the benefits of these 12V solar panels?

The benefits of solar panels of 12V are many. In today’s world it is obvious that energy is a very important component. You need energy for everything in life. This is the reason why people are finding the economical, sustainable, reliable, less polluting ways to avail natural sources of energy. Solar panels are the best ones among the above needs. The benefits are –

  • Sustainable source of energy
  • Renewable Energy
  • No Noise or Air Pollution
  • No Carbon Residues
  • Less Maintenance
  • Distributed Electricity Generation

Are you thinking how to select the best 12V Solar Panel ? Here are some tips to help you.

  • Check for total daily energy consumption

Before you buy a specific model of 12V or brand it is necessary for you to calculate your daily needs of the electricity. Your calculation process is not at all tough if you have the electrical appliances having the load consumption mentioned on them. If you use 4 lights of 10W 12V for around 3 hours a day, 1 television of 40W 12V for around 2 hours and a washing machine of 20W 12V for approximately 30 minutes, then your total load consumption will be 3×4×10W + 2×40W + 20W/2 = 210W per hour.

  • Panel Size

You need to check the size of your panel once you are done with your daily usage of energy. There are a wide variety of panels available in various sizes and shapes producing the same amount of energy.

 

  • Battery Capacity

The capacity of the battery is directly related to the amount of current produced by the solar devices. Along with that you have to keep in consideration about the size of the battery and also the battery capacity.

Even though the solar cells are costly, once you have a large energy producing panel then you do not have to look for the suppliers of electricity and pay monthly bills. Before you buy the panels you have to consider certain selection criteria such that the solar panel can be used efficiently. The battery which you desire to attach to the solar panel should be compatible enough with the current produced by these panels.

So now you have a clear idea about the 12V solar panel, maybe it’s time to consider buying one.
